Description

Technical Field

[0001] The utility model belongs to the field of waterway ecology, and in particular relates to an ecological waterway multi-level bank protection system. Background Art

[0002] Ecological slope protection is a slope protection technology that integrates the basic knowledge of engineering mechanics, soil science, ecology, and botany to support slopes or side slopes, forming a comprehensive slope protection system composed of plants or engineering and plants. After the excavation of the slope, plants are planted and the interaction between plants, rocks, and soil is used to protect and reinforce the slope surface. This method can not only meet the requirements for slope surface stability but also restore the damaged natural ecological environment. It is an effective means of slope protection and consolidation. Although hard revetments have high strength and good hydraulic properties, they will cause river channels to become closed and water bodies to be sealed. This not only destroys the natural landscape and hydrophilic function of the waterway, but also reduces the biodiversity of the waterway and reduces the self-purification capacity of the water body. Traditional ecological revetments use plants or a combination of plants and civil engineering. In addition to preventing the collapse of the waterway shoreline, they also enable water and soil to penetrate each other, promote lateral connectivity of the waterway, and have natural landscape effects. However, they are prone to soil erosion and lack good drainage and infiltration functions, resulting in average water purification effects. Utility Model Content

[0034] On the banks on both sides of the channel, reinforced concrete layer 1 and rock layer 2 are set up from bottom to top, and above the rock layer 2 is the original soil layer 3;

[0035] On the original soil layer 3 are arranged a primary filtration system 4, a secondary filtration system 5 and a tertiary filtration system 6 in sequence; the tops of the primary filtration system 4, the secondary filtration system 5 and the tertiary filtration system 6 are lower than the height of the original soil layer 3 at that location;

A water filtration branch pipe 7 is provided near the downhill side of the primary filtration system 4, the secondary filtration system 5, and the tertiary filtration system 6. The water filtration branch pipe 7 is connected to the waterway through the water filtration main pipe 8. A quick-release filter screen 9 is provided on the top of the water filtration branch pipe 7.

[0037] When the rainfall is heavy, the rainwater on the bank will first enter the water filtration branch pipe 7 when flowing downward. By setting up the first-level filtration system 4, the second-level filtration system 5 and the third-level filtration system 6, the rainwater erosion is gradually reduced, further playing a role in preventing soil erosion and protecting the ecological environment.

[0038] Preferably, the slopes of the reinforced concrete layer 1, the rock layer 2 and the water filtration main 8 are all 3°-5°.

[0039] Preferably, the primary filtration system 4, the secondary filtration system 5 and the tertiary filtration system 6 have the same structure, including reinforced gabions, a pebble ceramsite layer 41 and a planting soil garnet layer 42.

[0040] The original soil layer 3 forms a deep well, in which a reinforced gabion is arranged, and in which a pebble ceramsite layer 41 and a planting soil garnet layer 42 are arranged in sequence from bottom to top.

[0041] Preferably, the top of the planting soil garnet layer 42 is concave, and wetland plants are planted. Different vegetation is planted according to different situations, including but not limited to windmill grass, pennywort, and lily flower, etc. Local native wetland plants are planted first;

[0042] The thickness ratio of the planting soil garnet layer 42 to the pebble ceramsite layer 41 is 1:1;

[0043] The particle size of the pebbles and ceramsite in the pebble ceramsite layer 41 is 5-10 mm; the upper part of the garnet is planting soil with a thickness of 15-180 cm. The particle size of the garnet is 2-4 cm, which can quickly absorb rainwater, has many large pores and is not easy to be blocked, and can efficiently absorb pollutants in rainwater, thereby improving the purification effect of the ecological revetment.

[0044] Preferably, the planting soil can be artificially mixed with natural planting soil, domestic peat soil, cooked chicken manure, etc. in a certain proportion to form artificial planting soil. The proportion and dosage of each substrate are as follows:

[0045] Table 1 Volume ratio of each matrix in artificial planting soil

[0046]

[0047] Preferably, the water filter branch pipe 7 is provided with a plurality of water holes, and the diameter of the water holes is 0.5-1 cm.

[0048] Preferably, Figure 2 Figure 3 As shown, the quick-release filter 9 includes an upper mounting frame 91, a lower mounting frame 92, a quick-release part 93 and a filter 94. The filter 94 is mounted on the upper mounting frame 91.

[0049] The lower installation frame 92 is installed to the top of the water filter branch pipe 7, and the upper installation frame 91 and the lower installation frame 92 are connected by a quick release part 93; the quick release part 93 is a bead buckle, which is a commercially available part and can achieve the purpose of stability and quick release, quickly remove the debris of concern, prevent blockage, reduce the workload of staff, and improve work efficiency.

[0050] When this ecological waterway multi-level bank protection system is applied in actual projects, it should be combined with the overall design of the canal project and the waterway bank protection project, and integrated into the infrastructure such as the embankment road, horse path, upper and lower steps, and membrane bag concrete bank protection foundation in the actual project to achieve overall coordination.

[0051] Preferably, the selection of vegetation and the space for landscape greening are created in combination with the cross-sectional forms of different sections of the canal project. The dike garden road of the canal project is combined to create a waterfront viewing trail, the natural slope of the landscape is combined with the nodes to create a landscape step leisure platform, and the dike top road is combined with the waterfront roads along the line to create a leisure greenway.

[0052] The preferred principles for vegetation selection and greening design of the multi-level revetment system of the ecological waterway are as follows: (1) Respect the current status of the site: the original vegetation along the waterway is well maintained, and the greening design respects the current status, retains the plant species with good current status, and redesigns the greening for local areas; (2) Restore vegetation and greening to create a beautiful landscape: the existing slopes have exposed loess, and the greening design restores the greening of the slopes to create a beautiful waterway slope greening landscape. (3) Open the plant sight corridor: open the plant sight corridor, rationally sort out the plants that block the view, try to retain the existing large-scale tree site and open the sight space, try to avoid large trees, and if they cannot be avoided, transplant them to other sites within the red line nearby, sort out the plants along the line, and introduce the river view into the urban landscape. (4) Create distinctive tree species: the greening base along the waterway is good, but lacks color. The greening design adds flowering trees and palm trees, creates red, yellow, pink and coastal style landscape segments, and highlights the greening characteristics of the coast.

[0053] Preferably, three greening color vegetation planting plans are provided, namely red, yellow and pink flower series, to create the canal human landscape culture with corresponding colors.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
